US Patent 10108443 Low latency computational capacity provisioning

A system for providing low latency computational capacity is provided. The system may be configured to maintain a pool of virtual machine instances, which may be assigned to users to service the requests associated with the users. The system may further be configured to receive a request to acquire compute capacity for executing a program code associated with a particular user, determine whether the pool of virtual machine instances includes a container that may be used to execute the program code therein, and cause the program code of the particular user to be executed in the container.
